You are literally spreading disinformation.

CT has an official write-in candidate application and in the form it mentions that they do get counted.

Edit:

If a candidate has so registered, a vote may be cast by write-in ballot for such candidate by writing in the last name of the candidate for President and the last name of the candidate for Vice President or only the last name of the candidate for President; such write-in ballot shall be counted, and shall be in all respects effective, as a vote for each of the presidential electors representing such candidates for President and Vice President.
